Last night my cat who is around 7 month had diarrhea. I found blood in it and it looked like mucus. So i rushed him to the animal hospital. Checked his vitals everything seemed good. He does has an upper respitatory infection so he got an antibiotic. He tested negative for feline aids leukemia and parvo. So that wasnt causing his diarrhea. Anyway she gave me parasite treatment for him. But today hes throwing up and i dont know if it could be parasite related(they couldnt get a stool sample from him last night) so now i am wprried that they missed something. He did eat differently though i had to give him that crappy canned food friskies. Im wondering hes just sick from that. Does anyone have any advice. What can i feed him since hes throwing up now and having diarrhea??
